**EG1164 High Power Synchronous Rectifier Boost Power Supply Module, Maximum Efficiency 97%, Input Voltage 8\~50V, Output Voltage 8\~60V Adjustable, Maximum Power 300W or more, Switching Frequency 219kHz.(EG1164大功率同步整流Boost升压电源模块，最高效率97%，输入电压8~50V，输出电压8~60V可调，最大功率300瓦以上，开关频率219kHz。)** 白嫖了张嘉立创的彩色丝印券就随便画了个板试试，第一次打彩色丝印。(I got a free colour silkscreen voucher from JLC so I drew a board to try it out, first time I've ever done colour silkscreen.) 因为我测试设备有限（电源和负载都是最大300W），所以没法测更大功率，这个板最大带个四五百瓦以上的功率应该没问题。(Because I have limited test equipment (power supply and load are maximum 300W), so I can not measure the higher power, this board should not be a problem with a maximum power of more than 400 or 500 watts.) ## EG1164 Introduction The EG1164 is a high-voltage, high-current step-up synchronous rectifier DC-DC power management chip with an internal integrated reference power supply, oscillator, error amplifier, cycle-by-cycle current limiting control, half-bridge driver, etc. It is very suitable for high-voltage and high-current applications, and it can support up to 600V power supply voltage output with an external high-voltage MOS tube. - Boost synchronous rectification solution, support high voltage and high current solutions - An external capacitor can be used to set the operating frequency (0-300KHz). - 2-pin EN external resistor for flexible adjustment of start-up and shutdown voltage. - UVLO undervoltage lockout function: - Vcc pin turn-on voltage 3.65V - Vcc pin OFF voltage 3.6V - Week-by-week current limit control - Package: SOP16 EG1164 Datasheet Download：[https://pan.baidu.com/s/1JeLrXy9MAu78OpdTPdKRUw?pwd=t3ha](https://url.zeruns.tech/2B1qP) ## 实物图    ## 元件购买地址(Component Purchase Address) -

Input 32V, output 60V unloaded, ripple peak peak about 77mV.  At 32V input and 60V 2A output, the peak ripple is about 412mV.  Input 12V, output 24V no-load, ripple peak peak value of about 30mV.  At 12V input and 24V 2A output, the peak ripple is about 350mV.  At 8V input and 12V 2A output, the peak ripple is about 170mV.  ## schematic  ## PCB Top：  bottom：  ## Other open source projects recommended - STM32F030C8T6 Minimum System Board and Flowing LED (Schematic and PCB)：[https://blog.zeruns.tech/archives/715.html](https://blog.zeruns.tech/archives/715.html) - I drew a MSP430F149 minimum system board and open-sourced it.：[https://blog.zeruns.tech/archives/713.html](https://blog.zeruns.tech/archives/713.html) - 2007 National University Electronic Design Competition Power Supply Question: 30 to 36V Adjustable Boost DCDC Module (UC3843)：[https://oshwhub.com/zeruns/36v-sheng-ya-dcdc-mo-kuai-uc3842](https://oshwhub.com/zeruns/36v-sheng-ya-dcdc-mo-kuai-uc3842) - STC12C5A60S2 minimum system board/51 microcontroller temperature display and temperature control fan：[https://blog.zeruns.tech/archives/721.html](https://blog.zeruns.tech/archives/721.html) - STM32F407 standard library project template with ported U8g2 graphics library：[https://blog.zeruns.tech/archives/722.html](https://blog.zeruns.tech/archives/722.html) - CH32V307VCT6 Minimum System Board open source：[https://blog.zeruns.tech/archives/726.html](https://blog.zeruns.tech/archives/726.html) - LM25118 Auto Liftoff Adjustable DCDC Power Module：[https://blog.zeruns.tech/archives/727.html](https://blog.zeruns.tech/archives/727.html)[https://blog.zeruns.tech/archives/727.html](https://blog.zeruns.tech/archives/727.html)
